One of the major problems in networked settings is to identify and remove potentially malicious nodes.
For example, in social networks, malicious nodes may correspond to accounts created by malicious parties which spread social spam, hate speech, fake news, and the like, with considerable deliterious effects [1]}, [2]}.
Major social network platforms consequently devote considerable efforts to identify and remove fake or malicious accounts [3]}, [4]}.
Nevertheless, evidence suggests that the problem remains pervasive [5]}, [6]}.
Similarly, in cyber-physical systems (e.g., smart grid infrastructure), computing nodes compromised by malware can cause catastrophic losses, and mitigation through detection and removal of such malicious nodes is a major problem [7]}, [8]}.
